Reading Passage: The intricate relationship between human activity and natural ecosystems is an area of intense study. Overdevelopment in urban areas has led to a loss of biodiversity, as natural habitats are destroyed to make way for buildings and infrastructure. Research shows that the decline in species diversity can have cascading effects on ecosystem health. For instance, a more diverse ecosystem is often more resilient to diseases and environmental stressors. As scientists strive to understand these dynamics, they emphasize the need for strategies that balance urban growth with the preservation of natural environments.
